Maktstrukturer i svenskt näringsliv: En social nätverkstudie av delade styrelseledamöter i Sverige 1985 och 2005

This paper examines the interpersonal and intercorporate networks of interlocking boardmembers among Sweden's 50 largest publicly traded companies in 1985 and 2005. We find that both the interpersonal and intercorporate networks of 1985 are considerably more coherent and densely connected than those of 2005. The observed changes in social network structure are compared to changes in company ownership in Swedish publicly traded companies during the same period, and it is found that the observed changes in network density and cohesion can be related to a notable increase in the number of foreign board members. These results imply that the social organization of the Swedish system of corporate governance has changed notably during the period. Social network theory suggests that these changes can explain the greater demand for external regulation, decreased homogeneity of board members and increase in board member compensation observed under the period.

Pelletering av tallspån : grundläggande studier

Wood pellets are an upgraded product of residuals from several wood processing industries, for example saw mills and pulp industries. The pellets are produced by pressing the milled and dried sawdust to cylindrical units with a higher density than the initial raw material. Pellets have great benefits compared to the raw material: high energy per volume, good transport and storage properties and homogeneity. Several parameters collaborate in the whole process, which makes it complex. Wood is a heterogeneous material, chemically and structurally dependent on wood parts, habitat and storage procedures.

Breast cancer stem cells : evidence and contradictory views

This literature study aims to examine the existence of cancer stem cells in breast cancer. The cancer stem cell theory states that there is a hierarchical organization within a tumour, in which a small subpopulation of the cells can initiate new tumours and maintain tumour growth whilst the bulk of the tumour cannot. These tumour initiating cells have shown to possess many characteristics similar to those of adult stem cells, which is why they are often referred to as cancer stem cells. Both cell types have the capacity of asymmetric division and have shown to possess mechanisms of resistance to both apoptosis and cancer drugs. The cancer stem cell theory elucidates many biological aspects such as the heterogeneity of tumours and the relapse of many cancers after what appeared to be successful treatments.

Bilden av ledaren - en tolkning av fotografier i årsredovisningar

The visual representation of management (board of directors, chief executive officer and executive management) in annual reports is an area of scholarship that has not been explored much. In the present study a sample of 87 annual reports from business enterprises within a Swedish context, comprising about 300 photographs, was analyzed using an explorative method of analysis based on semiotics and grounded theory. The influence of the context on images raises a question discussed in the study: Should the photographs in the annual report be categorized as portraits, advertisements and others or should the annual report be regarded as a genre of its own? The photographs showed patterns of homogeneity regarding gender, dress, gestures, colours, pictorial compositions et cetera. The position of the (male) CEO is privileged, but he is also connected to the group through various means like dress and style, thereby further underscoring management as a male enterprise and demonstrating the importance of the suit and necktie in creating homosocial bonds.

Kunskapso?verfo?ring inom franchisena?tverk : En studie av utveckling och o?verfo?ring av kunskap inom franchisena?tverk

This case study has been conducted within the Swedish fitness chain World Class to explore the opportunities for knowledge development and transfers within franchise networks. We have interviewed the product manager at the World Class headquarter, the owner of a franchise club and a local product manager from the same facility. Our finding indicates that various forms of knowledge transfer occur within the World Class network, particularly in product development and sales. The transfer occurs within the framework set by World Class with regularly scheduled meetings. In addition informal networks provide other means of knowledge exchange between some units.

Att identifiera sig med en organisation : En studie om Posten Örebros organisationskultur

The purpose with this study is to identify an organizational culture at Posten Örebro based on Edgar H. Schein´s theory about the three levels of culture. These three levels consist of artifacts, espoused beliefs and values and basic underlying assumptions. Artifacts represent the visible and tangible of an organization and this level is the easiest level to identify. Espoused beliefs and values include common thoughts and ideals within the organization and are an aware, but not necessarily material, cultural level.

Interorganisatorisk styrning av leverantörsrelationer inom lågprismodebranschen: -En fallstudie av lågprismodeföretaget BikBok

This thesis concerns the control of outsourced interorganizational buyer-supplier relationships in the low-price fashion industry. A qualitative case study has been performed on two supplier relationships of a low-price fashion company. By identifying specificities of the industry and relating them to control problems and their implications on control solutions, the thesis has established a relation between industry specific characteristics and the way companies in the industry control their supplier relationships. The analysis is based on a theoretical framework created by Dekker (2004). Amongst other factors, the difficulty to define, quantify and measure the design variables of a fashion good, the high heterogeneity between individual products and the difficulty to predict the trend based demand, create high coordination requirements as well as appropriation concerns solved through extensive formal control.

Hyperglykemi hos kor med löpmagsdislokation :

The main interest of this study was to investigate whether there is hyperglycemia or hypoglycemia in cows suffering from abomasal displacement and to evaluate the effect of transport on blood glucose. Thirty-six cows with left- or right-sided abomasal displacement were included in the study together with 17 cows with other diseases for comparison. Fifteen cows with abomasal displacement and 7 cows with other diseases were sampled before transport. One third of the cows with abomasal displacement had hyperglycemia when the transport effects were corrected for. Separating this group in left- and right-sided abomasal displacement we found significantly higher blood glucose and insulin levels among cows with right-sided abomasal displacement. An explanation for this difference may be a strong stress response secondary to the right-sided dislocation.

Villkorslös Solidaritet? Om intresseheterogenitet inom Europafacken

This thesis deals with the supranational organization of European trade unions. The European trade union movement is, via its umbrella organization the ETUC, an institutionalized social partner within the European Union. The ETUC is a very diverse organization with great potential of conflicting interest among its members. This thesis therefore seeks to explore the dynamics and interest heterogeneity of the ETUC. Drawing on previous research and literature it formulates a number of hypothesises to test what variables that influence the member organizations policy preferences (i.e.

Folkbibliotekens webbplatsers grafiska användargränssnitt Kvalitativa intervjuer med webbansvariga

The web sites of Swedish public libraries display a high level of heterogeneity when it comes to design and graphical user interface. The thesis is based on the opinion that the visuals of a public library web site have implications for the user as well as for the library. The design of the graphical user interface influences the attention of the user and his/her ability to absorb information. Furthermore, there is a connection between the visuals and the users opinion about the credibility of the content of the web site, as well as of the organisation itself. The research question is: Which factors may have an impact on the design of the graphical user interfaces of a public library web site? The purpose is to create an understanding for these factors and emphasize them.

Från "Zigenarfrågan" 1956 till "Romers rätt" 2010 : En studie om den strukturella diskrimineringen av romer i två statliga utredningar

This thesis will deal with the development of the situation of the Roma minority in the Swedish school system in the period between 1954 to 2010, based on two Swedish Government Official Reports of the group's situation in the Swedish schools. The study is done by the report Zigenarfrågan (SOU 1956:43) and with the report Romers rätt (SOU 2010:55). The report Romers rätt was written by the Delegation for Roma issues and gives an updated picture of the situation of Roma in the Swedish school system. The state investigation Zigenarfrågan, is also important as the latter resulted in the Roma children enrolled in Swedish schools. This work will look at the various governmental investigations by the theory used for analysis called ?structural discrimination theory?.

Västra Götalands kommunala kriskommunikation. Ett intersektionellt perspektiv på krisberedskap

This thesis examines the municipalities of Västra Götaland and the way they are prepared for crisis communication towards people with a foreign background. Over the past years there have been several studies that have examined the issue of crisis communications towards minorities but these are often focused on the target group. In this study, I focus on the authorities' actions. The theoretical approach is primarily an intersectional one and in this way the thesis is centred on the creation of different categories, the relationship between these categories and the possibilities working with these at the municipalities.On behalf of Region Västra Götaland, this investigation began with a survey that went out to the communications officers in charge of the crisis communication in each municipality. The ambition was to clarify the preparedness of each one and show how they relate to one another.

Influence of the habitat on the potential for cannibalism and population dynamics in stream-dwelling European grayling (Thymallus thymallus L.)

Cannibalism can have major influence on fish population dynamics. A prerequisite for cannibalism is that the cannibal and the potential victim meet, and besides density effects, the encounter rate between cannibals and their victims is therefore also largely dependent on habitat use and habitat heterogeneity. In this study I quantified and compared the potential for cannibalism in stream-dwelling European grayling populations in three rivers in Jämtland by means of habitat classifications. I also analyzed population dynamic consequences of varying the potential for cannibalism in terms of intensity, using a physiological structured population model. Findings based on habitat characteristics were that the potential for cannibalism is in general not favourable in these types of streams.

Den statsvetenskapliga diskursen : En innehållsanalys av statsvetenskapliga doktorsavhandlingar 2000-2013

A possible "discursive turn" is believed to have been observed within Swedish political science in later years. The purpose of this study is to examine whether or not such a turn has actually taken place, in order to further determine if a resulting theoretical homogeneity poses a risk to the ability of Swedish political science to identify and respond to its full width of possible research problems, and to determine its perspectives on both these problems and the results that are later communicated to the general society. To do so, the study poses the following primary research question:"Has a discursive turn occurred within Swedish political science?"This question is then broken down into two specified research questions."Has discourse analysis become a more common approach for doctoral dissertations in political science during the period of 2000-2013?""Have ideas corresponding with discourse theory become more common within doctoral dissertations in political science that are not pure discourse analyses during the period of 2000-2013?"These questions are then answered by examining all known 406 doctoral dissertations in political science published in Sweden during the 21st century up until (and including) the year of 2013, using two forms of content analysis, one manual and one computer-assisted. The study finds no clear evidence of a discursive turn in Swedish political science since the turn of the century.

Heterogenitet i skogsbestånd : faktorer av betydelse för artrikedom och förekomst av småfåglar

Denna studie undersökte hur heterogenitet i skogsbestånd samt omgivningsfaktorerna träddiameter, variation i träddiameter, död ved och lövinslag påverkar förekomsten av 18 skogsfågelarter i södra Sverige. Fågelinventeringen utfördes med hjälp av linjetaxering längs 100 meter långa transekter. Omgivningsfaktorerna mättes i varje transekt i fem provcirklar med diametern 10 meter. Analysen av träddiameter visade att det främst var diameter på barrträd, men inte på lövträd som inverkade på förekomsten av fåglarna. Sambanden mellan diameter på barrträd och totalt antal fågelarter var övervägande negativa vid 0-30 centimeter i diameter och övervägande positiva vid 30-80 centimeter i diameter.
